The United States is probably the only country with a holiday that celebrates all of its presidents — this year’s observance is set for February 18. Other countries have holidays that celebrate individual leaders. Take North Korea for example. The country’s major holidays include Kim Il-sung’s Birthday (decreased president and the grandfather of the current leader), Kim Jong-suk’s Day (the grandmother of the current leader), and Kim Jong-il’s Birthday (decreased leader and the father of the current leader). North Korea is planning to add another public holiday to its calendar — it’s not hard to guess whom it will honor.
